Not bad, but I'm not sure I buy the parallelism because, although bitcoin was created as a currency, it is hardly used as such. It is often compared to the asset market, with a total value of $900 trillion, which I think is more accurate given the current state of affairs.
Bitcoin is everything though. If people were using the USD more as an asset, would that make it stop being a currency? Not really. But yeah it should be also compared with the assets as well, not just the money supply.
